Gershwin: Stack-based, Concatenative Clojure

The Gershwin programming language is a stack-based, concatenative language with a Clojure runtime that targets the JVM. It features a fusion of Clojure datastructures, namespaces and concurrency semantics with an API inspired by the Factor concatenative programming language. With seamless Clojure interop, Gershwin can leverage all the power and reach of the Clojure/JVM ecosystem while also providing the unique features of stack-based, concatenative languages: composition by code concatenation, point-free expressions, data-flow combinators, and simple, powerful code factoring.

This presentation provides an overview of the features and implementation of Gershwin, with explanations of Clojure and Factor topics as they relate to Gershwin's implementation. The presentation media itself will be produced by a Gershwin program, which will be the example codebase used to demonstrate core Gershwin concepts including interactive REPL development, defining new words (functions), quotations, Clojure interop, code organization, and building a Gershwin project.
